PLOW.

SPECIFICATION forming part of Letters Patent No. 732,302, dated June 30,1903.

Application filed April 6, 1903- Serial No. 151,213. (No model.)

To 00% whom it may concern:

Be it known that we, PER J. JOHANSSON and LAGE L. J oNssoN, bothcitizens of Sweden, and residents of West Ohelmsford, in the county ofMiddlesex and State of Massachusetts, have jointly invented certain newand useful Improvements in Plows, of which the following is aspecification.

This invention relates to improvements in plows adapted for usepreparatory to planting potatoes, beets, carrots, or similar vegetables,and has also for its object the pulverizing of the earth and covering ofthe seeds after planting. The device is furthermore adapted for use indigging up the said vegetables when ripe, as will hereinafter be morefully shown and described, reference being had to the accompanyingdrawings, wherein Figure 1 is a side elevation of the improved plow,partly shown in section. Fig. 2 is a horizontal section on the line 2 2shown in Fig. 1. Fig. 3 is a cross-section on the line 3 3 shown in Fig.2, and Fig. 4 is a detail top plan View of the pulverizer attachment shown as detached from the bill of the plow.

Similar letters refer to similar parts wherever they occur on thedifferent parts of the drawings.

In the drawings, Arepresents the plowbeam, to the forward end of whichis attached the clevis B, as usual.

-C represents the handle-post, the lower end of which is firmly securedto the lower sole portion or runner D, which, when made of wood, ispreferably provided with a metal shoe d, as shown in Figs. 1 and 3. Tothe post 0 is secured in a suitable manner a handle Efor guiding theplow while in use. In practice the post 0 terminates at its upperend asa projection O, which may be used as arcinholder during the use of theplow, as may be desired.

The rear end of the beam A is pivotally connected at a to thehandle-post O, as shown in Fig. 1.

F is the colter, the lower end of which is secured in a suitable mannerto the runner D. The upper end of said colter is connected to thehandle-post O by means of a stay or The colter F is pivotally connectedto the plow-beam A by means of a bolt f, provided with a thumb-nut f.(Shown in Fig. 1.) A series of perforations f f are made in the colter Ffor the purpose of adjusting the position of the beam F relative to saidcolter according to the depth of the furrow desired to be plowed, whichmay be determined by the vertical adjustment of the forward end of theplow-beam.

To the forward end of the base portion D is secured the triangular orsimilarly-shaped plowshare H, the sides of which are inclined from thecenter in lateral directions, as shown in Figs. 1, 2, and 3. To theupper side of the share H is secured a bar I, the rear end of which ispreferably forked, as shown in Fig. 2, and suitably connected to thecolter F, as shown in said Figs. 1, 2, and 3. In connection with saidplowshare is used a pulverizer adapted to disintegrate and break up theearth as it is being cut and turned over by the said share, and suchdevice is preferably made as represented in detail in Fig. 4:. Itconsists of a Y-shaped plate of metal K, having a tongue 7c, attached ina suitable manner to the share H and provided with rearwardlyextendingflaring cars 76 as shown. said pulverizer is secured to the runner D,share H and bar I by means of a suitable fastening-bolt L. (Shown inFigs. 1, 2, and 3.)

In using the plow the beam A is adjusted in a vertical plane and securedto the colter F in position according to the depth of fur.- row desiredto be made. As the plow is moved forward the point of the share 11 iscaused to enter the earth at a suitable depth when guided by theoperator, causingthe earth to be turned over and deposited on oppositesides of the furrow, and such overturned earth will be disintegrated andpulverized by the outwardly and upwardly flaring cars k 70- ready forreceiving the seeds to be planted. After the seeds have been planted inthe furrow made the plow is drawn between the furrows, causing the seedsto be covered by the action of the ears 70 k, which cause the pulverizedearth to fall over the seeds in the furrows as the plow is being drawnonward by the draft-animal.

The device is also useful as a drill-plow for the purpose of digging upthe tubers when ripe.

The v The frame portions A O D are shown in the drawings as being madeof wood; but we do not desire to limit ourselves to such exactconstruction, as such parts maybe made of metal without departing fromthe essence of our invention.

\Vhat we desire to secure by Letters Patent and claim is- 1. In a plow,a beam A,'a colter F, adjustably connected to said beam and a handlepost0, pivotally connected to said beam, and secured to the upper end ofsaid eolter, in combination with a pointed and outwardlyfiaring share H,and rearwardly and outwardly extended pulverizer-ears 70 70,substantially as and for the purpose set forth.

2. In a plow, in combination with a base or runner D and a eolter F,secured thereto, a duplex and pointed share H, and a bolt L,
